RFR: 8319928: Exceptions thrown by cleanup actions passed to reinterpreted segments should be ignored [v2]

[Maurizio Cimadamore]

> This simplePR tweaks the factory which wraps custom cleanup actions passed to `MemorySegment::reinterpret`, so that any exception thrown by the custom cleanup is swallowed when the arena is closed.
> 
> This aligns the behavior of confined/shared session with that of implicit session (as implicit sessions are backed by a `Cleaner`, there is no way for cleanup exception to bubble up).

Maurizio Cimadamore has updated the pull request incrementally with three additional commits since the last revision:

 - More javadoc tweaks
